The effect of the mixing state of black carbon (BC) on light absorption is of enduring interest due to its close connection to regional/global climate. Herein, we present concurrent measurements of both BC absorption enhancement (E-abs) and the chemical mixing state in southern China. E-abs was obtained by simultaneous measuring the light absorption coefficient using an aethalometer before and after being heated. The observed E-abs was categorized into non- (E-abs <= 1.0), slight (1.0 < E-abs <= 1.2), and higher (E-abs > 1.2) enhancement groups, and it was compared to the mixing state of elemental carbon (EC) particles detected by a single particle aerosol mass spectrometer (SPAMS). The individual EC-containing particles were classified into four types, including EC with sodium and potassium ion peaks (NaK-EC), long EC cluster ions (C-n(+/-), n >= 6) with sulfate (EC-Sul1), short EC cluster ions (C-n(+/-), n < 6) with sulfate (EC-Sul2), and EC with OC and sulfate (ECOC-Sul). NaK-EC and EC-Sul2 are the dominant EC types. Slight enhancement group is mainly explained by the photochemical production of ammonium sulfate and organics on EC-Sul2 during afternoon hours. In contrast, the higher E-abs is primarily attributed to the enhanced mixing of ammonium chloride with NaK-EC during morning hours, without photochemistry. The characterization of source emissions indicates that NaK-EC is likely from coal combustion and is associated with a relatively higher amount of ammonium chloride. To our knowledge, this is the first report to state that EC particles associated with ammonium chloride have a relatively higher E-abs. (C) 2020 Elsevier B.V. All rights reserved. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 707-36-8, you can contact me at any time and look forward to more communication.
